If there's any problem, please feel free to ask us for more information.

Parameters
Input Voltage: DC 6-30V
Output Voltage: DC 0.5-30V adjustable
Output Current: 4A (max), adjustable, recommended to use within 3A.
NOTE: If the output current or power is more than 2.5A or 35W, you’d better enhance the heat dissipation.
Output Power: 60W (max), recommended to use within 50W.
NOTE: Please reduce the power when the difference between input and output voltage is large.
Operating Temperature: -20~+70℃
NOTE: Pay attention to the temperature of the power tube when using this module, please strengthen heat dissipation if it exceeds 70℃.
Wiring: Terminals or solder terminals; VIN means input; VOUT means output.

Protections
Short circuit protection: Yes (currently constant current value)
Over temperature protection: Yes (automatically turn off the output if over-temperature)
Tips: There is an additional fan opening on the bottom of the module shell, which can be used to add a fan.
Input reverse polarity protection: Yes
Output anti-backflow: Yes

Voltage Calibration
If you find that the measuring values are not accurate, please do as follow:
In the condition of power off, hold press the “SET” button and power on to enter the voltage calibration mode, at this time the LCD screen starts to flash.
Then release the “SET” button, press the “SET” button to increase voltage value while press the “ENT” button to reduce, till the input voltage value is correct. e.g. If input voltage is 12.65V, adjust the voltage value to 12.65V.
It will automatically be saved after 2 seconds, then power off the module to finish calibrating.
